Modeling hydrodynamic regime of the technogenic aquifer within the Noyabrsky site of the Aikhal mine

The Noyabrsky site is used for the injection of highly mineralized drainage waters formed during development Aikhal kimberlite pipe (Republic Sakha (Yakutia), Russia). water injected into wells since 2013 has a localized intrapermafrost technogenic aquifer. Taking account porosity parameters permafrost reservoirs, as well confirmed useful capacity site, its operation planned to continue until 2044 at very least. Despite relatively small volumes (up 430 m3/day), forecasting dynamical changes in hydrodynamic regime horizon challenging task, which significant practical importance provision environmental and industrial safety. assessment anthropogenic impact, subsequent dynamics within were carried out by modeling methods Modflow software. brine lens today characterized uneven parameters, due peculiarities heat mass transfer when using injection. Based on results predictive conclusion can be derived that use method mine strata allows reduce influence degree mining production operations geological environment studied area through localization an intentionally limited, area, where out, environment, preventing brines from entering surface 2044.
